Setup equations
1) x  7 + 3 + 6  8 + 1  6 = 3
x + 10  21 = 3
x  11 = 3
x = 13
2) x  12.00 + 15.00  7.00  8.50 + 8.00
+ 2.00 = 22.25
You solve
3)
Miguel
x + 15  4 + 6  17 + 22 + 14 = 40
Yoshi
x + 12  4 + 33  7 = 40
You solve
4)

I think in a question 2 the answer is 24.75. Correct?
What about a question 4. 3:35 is the latest time she should leave her house?
